Does exactly what it's supposed to.
Easy to use and did the job. Unwrap it, letit loft for about an hour or so, tack it in, throw some drywall up. Great product to helped insulate between two bedrooms. More for sound than anything.

Not 13 pieces - only 9
I purchased 4 units of the R-13 unfaced batt yesterday. The packaging and the description both say 13 pieces per sell unit. There are only 9 pieces in each. False advertising or a typo? The cost is $6.05/piece instead of $4.19/piece. Can I get a refund? Also, this product should be pulled or relabeled. I also bought 4 units of the R21 unfaced batt yesterday. Those state 8 pieces per unit and they do have 8 pieces.
Great Insulation
This fiberglass batt insulation provided the needed thermal and sound consistency.

Easy to use and cheaper than the Kraft paper one.
Easy to use. You can unroll it on the ground and cut it with a box cutter if needed. I used to insulate my attic over my garage. Perfect height to go between the 2x4s without rising above them. This lets you easily lay plywood down if you want a floor. The one with paper on one side would be slightly easier to work with but the price difference made this the better financial choice.

Does the individual package contain 11 pieces of 16"x48" insulation, or 5? The title and specifications are different from the picture.
